Intrabuilding Pathway Element

An itrabuilding pathway element is a cabling support vessel that typically connects one space to another or runs the span of a common routing cable route, but resides in one space. The format for the intrabuilding pathway element shall be fs-UUU.n.d(q) or fs1/fs2-UUU.n.d(q), where:

fs = Identifier for a space which is derived by combining the level and the building area in which the space is located. The space can be represented by the space ID (if present) or a user defined identifier (descriptor).

fs1 = Identifier for the space containing the termination of one end of the horizontal pathway, typically the most central or lowest alpha-numeric identifier

fs2 = Identifier for the space containing the termination of the other end of the horizontal pathway, typically the least central or highest alpha-numeric identifier

UUU = a user defined identifier referring to the type of element (descriptor)

n = two to four numeric characters identifying the pathway element (major ID)

d = detail information such as port, sub-duct, optical fiber and pair (minor ID)

q = qualifying information

The pathway records shall contain the following information:

intrabuilding pathway identifier (primary indexing identifier,

e.g., 3A/3B-CT01)

pathway type (e.g.: Cable Tray)

pathway fill (e.g.: 20%)

pathway loading

cable records

space record1 (e.g.: 3A)

space record2 (e.g.: 3B)

grounding record

Additional items of information desired by the system owner or operator may be added to each record, such as:

pathway length (e.g.: 40m (132ft))

pathway max fill (e.g.: 40%)

pathway max load

pathway condition

number of bends

firestopping records
